Adatoms and clusters of 3d transition metals on graphene: Electronic and magnetic configurations

T. Eelbo, M. Waśniowska, P. Thakur +8

We investigate the electronic and magnetic properties of single Fe, Co, and Ni atoms and clusters on monolayer graphene (MLG) on SiC(0001) by means of scanning tunneling microscopy…

Strong Effects of Cation Vacancies on the Electronic and Dynamical Properties of FeO

Urszula D. Wdowik, Przemysław Piekarz, Krzysztof Parlinski +2

We report pronounced modifications of electronic and vibrational properties induced in FeO by cation vacancies, obtained within density functional theory incorporating strong local…

Exotic spin orders driven by orbital fluctuations in the Kugel-Khomskii model

Wojciech Brzezicki, Jacek Dziarmaga, Andrzej M. Oleś

We study zero temperature phase diagram of the three-dimensional Kugel-Khomskii model on a cubic lattice using the cluster mean field theory and different perturbative expansions i…

Growth of High-Mobility Bi2Te2Se Nanoplatelets on hBN Sheets by van der Waals Epitaxy

Pascal Gehring, Bo F. Gao, Marko Burghard +1

The electrical detection of the surface states of topological insulators is strongly impeded by the interference of bulk conduction, which commonly arises due to pronounced doping…

Defect states and spin-orbital physics in doped vanadates Y1-xCaxVO3

Peter Horsch, Andrzej M. Oles

We present a model for typical charged defects in weakly doped Y1-xCaxVO3 perovskites and study how they influence the magnetic and orbital order. Starting from a multiband Hubbard…

Point-contact spectroscopy in Co-doped CaFe2As2: nodal superconductivity and topological Fermi surface transition

R. S. Gonnelli, M. Tortello, D. Daghero +4

We performed point-contact Andreev reflection spectroscopy measurements in Ca(Fe_{1-x}Co_x)2As2 single crystals with effective x=0.060 +- 0.005. The spectra of ab-plane contacts sh…
